Flex整合Spring
原文:http://ljhzzyx.blog.163.com/blog/static/383803122008111853323499/
利用别人写的SpringFactory类,将Flex和Spring整合在一起,配置步骤如下:
1.添加Spring,在web.xml文件里添加配置
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
2.在flex的services-config.xml文件里添加Spring工厂
<factories>
<factory id="spring" ref="dataSource"/>
</bean>
4.在flex的远程对象配置文件里配置远程对象,这里要指定远程对象的创建工厂为第2步配置的工厂,远程对象的source要指向Spring里定义的bean
<destination id="test">
<properties>
<factory>spring</factory>
<source>testClass</source>
</properties>
</destination>
5.在页面就可以使用远程对象了
private function send():void{
test.doSomething(...);
}
...
<mx:RemoteObject id="test" destination="test" result="..."/>
贴上SpringFactory类:
package com.flex.factories;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.NoSuchBeanDefinitionException;
import flex.messaging.FactoryInstance;
import flex.messaging.FlexFactory;
import flex.messaging.config.ConfigMap;
import flex.messaging.services.ServiceException;
public class SpringFactory implements FlexFactory{
private static final String SOURCE = "source";
public void initialize(String id, ConfigMap configMap) {}
public FactoryInstance createFactoryInstance(String id, ConfigMap properties){
SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
return instance;
} // end method createFactoryInstance()
public Object lookup(FactoryInstance inst){
SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;
return factoryInstance.lookup();
}
static class SpringFactoryInstance extends FactoryInstance{
SpringFactoryInstance(SpringFactory factory, String id, ConfigMap properties){
super(factory, id, properties);
}
public String toString(){
return "SpringFactory instance for id=" + getId() + " source=" + getSource() + " scope=" + getScope();
}
public Object lookup() {
ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());
String beanName = getSource();
try{
return appContext.getBean(beanName);
}catch (NoSuchBeanDefinitionException nexc){
ServiceException e = new ServiceException();
String msg = "Spring service named '" + beanName + "' does not exist.";
e.setMessage(msg);
e.setRootCause(nexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
}catch (BeansException bexc){
ServiceException e = new ServiceException();
String msg = "Unable to create Spring service named '" + beanName + "' ";
e.setMessage(msg);
e.setRootCause(bexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
}
}
}
}
